Lake ecosystems are essential for human wellbeing and development for their capacity to provide multiple ecosystem services (ES). However, because of an anthropogenic-driven ecologic degradation, the sustainable supply of lake ES is at risk. It is, therefore, necessary to restore lake ecosystems and their ES for the sustainable support of future generations. There is a lack of knowledge about mapping lakes ES at the global level. This study conducts a systematic literature review focused on mapping lake ES. Initially, 617 studies were identified. However, only 30 studies were considered. The 30 studies identified were published between 2015 and 2021. Most of them were conducted in Asia, followed by Europe and America. The selected works covered all three Common International Classification of ES sections (regulating and maintenance, provisioning and cultural). We identified a similar number of works carried out in all the sections. Most of the studies were performed at a regional scale and focused on ES supply. Methodologically, an equal number of works followed qualitative and quantitative approaches. In total, 13 different methods were identified. The most used were the ES value (ESV) and biophysical modelling. Less than half of the works that applied the ESV method mapped all the ES analysed. Among the studies assessed, most were focused on environmental and socio-economic aspects. Only 1 study attempted to validate the results. Overall, 16 studies assessed the drivers of change impacts on ES supply. Nevertheless, only 1 considered climate change. The other 15 only considered land-use changes. This systematic review showed that a small number of works focused on lake ES mapping. Although challenging, there is an urgent global need for studies in this domain.
